I have one, provided that the UK model is the same or similar to the one you are looking at.
Remember it's basically a Ford platform.
I'm very happy with mine. No idea about the mileage, as I don't care enough (and don't drive enough) to bother recording it. No mechanical/maintenance issues other than annual service/road testing - I do jet wash under the wheel arches when I clean it, but no signs of rust (I have a 2009 model bought in 2011) I'm happy with performance (it's pretty nippy) and space (me and a medium size dog). Possible negative is that it is perhaps a little noisier inside than the ideal, but for a small cheap car something has to give, right?
I'm planning on keeping mine until it or me dies.
